The Federal Ministry for Economic Affairs and Energy (BMWi) promotes measures to increase energy efficiency.
You can receive a loan of up to EUR 25 million for the following measures:

• Energy-efficient refurbishment of a non-residential building in the municipal and social infrastructure to a KfW efficiency building
  
  or
• Individual measures to improve the energy efficiency of non-residential buildings in the municipal and social infrastructure:
• Insulation of walls, roof surfaces, storey ceilings and floor surfaces,
• Renewal and refurbishment of windows, curtain walls, external doors and gates,
• Measures to improve thermal insulation in summer,
• Installation, replacement or optimization of ventilation and air-conditioning systems,
• Initial connection to local or district heating,
• Renewal or optimization of heat/cold distribution and storage,
• Renewal or optimization of heat/cold generation,
• Replacement and/or optimization of lighting,
• installation or optimization of measurement, control and regulation technology and building automation.

The funding covers measures for the preparation, implementation and commissioning of the funded measure, such as ancillary work or planning costs.

You will not receive funding:

• for the costs of a heat generator based on oil as an energy source,
• for cash loans and debt rescheduling of already completed and fully financed projects,
• if you have already started the measure before submitting the application.

There is a benchmark for energy-efficient buildings, the KfW Efficiency Building Standard. The lower the number, the more efficient your building is and the less energy you need.
The following standards are subsidized:

• KfW Efficiency Building 70,
• KfW Efficiency Building 100,
• KfW Efficiency Building Listed Building.

The amount of the repayment subsidy depends on the KfW Efficiency Building standard of your measure:

• KfW Efficiency Building 70: You receive a repayment subsidy of 27.5 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 275 for each square meter of renovated net floor area.
  
• KfW Efficiency Building 100: You receive a repayment subsidy of 20 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 200 for every square meter of renovated net floor area.
  
• KfW Efficiency Building Monument: You will receive a repayment subsidy of 17.5 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 175 for each square meter of renovated net floor area.
  
• For individual measures, you will receive a repayment subsidy of 20 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 200 for each square meter of renovated net floor area.

You will only receive the repayment subsidy once you have completed your measure and provided proof of completion to KfW. To do this, you must prove

• that you have used the money for the measure applied for,
• that you have achieved the KfW efficiency building standard or the energy savings.

You must keep all invoices and documents relating to the measure.

Applications for funding are processed by the Kreditanstalt für Wiederaufbau (KfW).

You have no claim to approval of the funding.
